3 Claims. '1

This invention relates to building construc- -tions' and i has for .its :main object 'to i provide a novel method and meansto fabricate 'brick,'stone or other designs one. wall; column, posh-and the like, in a more efiicientyunique, originalgand highly economical manner than "has been: proposed heretofore.

Another "object of my. invention is to provide a process or method, and means forthesame; a

indicated hereinbefore, *which "enables the -.user to apply it for various :spaces;sizes'andiorms, and on various objects, like walls, columns, 1 etc.

Still a further object of myinvention is to provide a method and mean for producing brick; stone, or other eifects on buildings with a fraction of the cost of an actual-brick or stone construction.

A further object of my invention is toprovide such a brick, stone and the like efiecton a building wall, which at the same time will insulate the building against the cold of winteror the heat of the summer, and also fireproofing waterproofing, termite proofing and weatherproofing .a frame.

.Still "other-objects :of this invention will be. apparent as-the specification of thesameaproceeds or will be pointed out therein.

In thedrawings forminga-partof this specification and accompanying-thesame:

Fig. 1 is a fragmentary sectional view .of 1a dicates the wooden wall of a ."bu'ildingarid the like.

In practicing my invention I first apply on said wooden wall as foundation, a layer ll of felt paper. Then I apply a layer 12 of wire mesh which may be supported by nails 29 across the face of the paper, and upon the wire math I now apply a coat of cement it. While said coat is almost dry I apply by staples or special paste fluids thereon a layer of my brick pattern as indicated at M. This patternI- preferably make :of cardboard impregnated with oil'or'waxand isporous toretain wetness and' preferably being of'a thickness of or A; inch thick or to suit the thickness of brick height desired.

As clearly shown in Figs. 2 and 3 the pattern of the brick iscutput :of thacardboard-asdndicated atltjeaving the'intact, horizontal-land .vertical bars l6 and 11, respectively.

My pattern It ris preferably prepared inia long rolled .upi form 'or in specialisize cuts and in units of about :three feet wide and three-to thirty feet long-rolls, and islater cut upto suit in appropriate pieces, to cover and "fit any Wall space orotherspaces. Pattern designs cftsingle :and half bricks are also supplied for around windows and for commercial" ornamentation.

The first coat of cement I3 will be-al-lowedto dry for about six hours and pattern Hi will then be adhered-by staples or by attaching by. pasting vfluidstoit. The pattern is then dampened .by a spray of water after which l apply-afinal layer 18 of a mixture of powdered brick cement,-sma1l granules of granite to create concrete brickform materialof a desired coloring, this in awet mixed condition, over the entire surface of the *first cement-covering as well as on'the pattern. This last surface coating is permitted to dry about The' aforesaid last'brick-form material .is pressed' well over: thefirst' surface and pattern for better "brick .forming performance.

The last brick-form coat having been "permitted to dry for about twelve ."hours is now thoroughly water-sprayed: and water soakedzfor about fifteen minutes. This water :spray .will enter the 'pores of the cementandth'oroughly soak the pattern paper causing it to swelliand expand. Thelast coat material on the brick 'patterneiiects f is completely dried in :the -"meantimefhowever; the material .on 'thepattern paper has notoried except only ina small measure since cement w'ill not adhere or dry "on a wet cardboard materialgoil or waxed surface. "The surface over the pattern istherefore soft,=powdery and undried. The brick-pattern material over the cement ha completely dried thus forming a brick design form. The additional last sprinkling and wetting of the entire finished surface only tends to harden the brick effect further as the brick contracts, loosening itself from the softer material covering the pattern paper. The sprinkling of the wall on the last coat material causing the pattern paper to expand and immedijately thereafter the pattern is easily re- "n'iov 'e'd, leaving a clean out brick clesignwith all tern is removed in clear and perfect lines of the color of the original cement coat.

In a similar manner, stone or other designs may be produced by appropriate patterns. Similarly, shingles or other effects may be produced on a wall or even a roof. Also my method may be applied on rectangular, polygonal, or round posts, columns or corners as well a many different ornamental effects may be produced by my method and process.

If the wall is made of cement blocks or stucco the felt and wire mesh layers H1 and I2 maybe omitted and the cement layer 13 directly applied on the wall. For marble effects, I may use a combination including marble powder and heavy coat paint covers for similar and other effects. A wire brush with widely spaced bristles 21 may be drawn across the still soft last coat application to produce score lines 22, see Fig. 6.

One highly satisfactory frame, wood walled house was finished by covering the walls with a black fifteen pound felt paper held by nails 23 holding usual thin metal discs 24 outside the felt and driven into the wood. Then a wire mesh lath was applied and held in place by headed nails driven into the wood. This was covered by a suitable cement stucco mortar troweled on and allowed to dry about six hours. On this was applied the pattern to show brick joints consisting of a skeleton of paper board used and previously described, of an inch thick, and was mounted with staples in the design desired. Following this, the wall and especially the pattern was moderately wetted.

Upon this skeleton mounted pattern surface and including all the surface was troweled a wet paste of ground brick and granite particles and cement and coloring to cover the entire wall. After this final coating had hardened about twelve hours, the entire wall was wetted thoroughly for about fifteen minutes and directly thereafter the pattern was removed with ease leaving perfect brick patterns and showing clearly the mortar lines between the brick of the opposite color of the first cement coat. The effect was that of a finely finished cleaned brick house wall.

It will be understood that the basic novelty.

appearance of brick, and the exposed surface of said facing will be evened and if necessary gone over with devices to make it resemble brick or of other desired effects, after which the patterns will be removed and the desired brick or other design will be shown by grooves of mortar lines.

As has been mentioned hereinbefore, in this 4 manner large surfaces of a wall may be reornamented and made to appear as brick or other stone wall with mortar lines in an efficient,

.easy, inexpensive and quick manner as against the slow laborious, expensive methods heretofore proposed for such ornamentations of walls.

In the preferred practice of my invention I prepare specific foundations for said pattern and the ornamental face layer to be formed through the use of said pattern in the manner indicated, and said face layer is evened over the pattern,

saidpattern then being removed after the operations described.

As has been specifically described I prefer to have the pattern made of cardboard material adapted to be soaked with water and to be easily removed in such condition.

Having thus described certain embodiments of the invention in some detail, what is claimed is:

1. A process for preparing an ornamental face on a wall including mortar lines, consisting in applying a removable pattern having bars therein corresponding to the mortar line design to be produced on the wall, filling the spaces between the mortar line bars with an appropriate plastic material, permitting said plastic material to harden and then removing said pattern whereby mortar lines of predetermined depth will be produced between the filled in portions of the 'pattern, said pattern being of water absorbing charactenand being easily removed when soaked with water, and applying water on the ready face on the wall for easier removing of the pattern.

2. In a process for producing an ornamental face on a wall, the steps of securing a removable pattern on the wall, said pattern having apertures therein corresponding to the design to be produced, filling said apertures with a plastic composition, permitting said composition to harden, wetting the pattern, said pattern being adapted to absorb water and to be soft, easily tearable and removable in such condition.

3. The process, method and system of preparing an ornamental face on a wall which includes applying a coat of cement, applying to the still soft cement an oiled paper pattern of crossed resisting lines in the pattern of dividing lines of brick, applying a colored cement coat to the cement over the pattern so that the drying cement coat growing harder will separate itself through contraction from the pattern and the pattern will-absorb the moisture from the drying cement coat, and applying water spray on the pattern for an easy removal.
